STOPPER FOR WASHBASINS OR BATH-TUBS.

SPECIFICATION forming part of Letters Patent No. 630,011, dated August1, 1899.

Application filed June 16, 1899. Serial No. 720,784. No model.)

To all whom it may concern:

Be it known that I, PERRY 0. SMITH, a citizen of the United States,residing at Indianapolis, in the county of Marion and State of Indiana,have invented certain new and use ful Improvements in Stoppers for lVashbasins orBath-Tubs, of which the following is a specification.

This invention relates to improvements in stoppers for washbasins andbath-tubs; and the object is to provide a flexible disk to close theoutlet, with guides on the two opposite sides of the disk to facilitatethe placing and retention of the stopper over the outlet-passage and topermit the reversing or use of both sides of the disk. 7

The object, also, is to provide means whereby the chain which attachesthe stopper to washstand or bath-tub will be connected centrally of theguide and disk and removably secured to permit of change in the side ofits attachment.

I accomplish the objects of the invention by the mechanism illustratedin the accompanying drawings, in which-- Figure 1 is a top or plan viewof my invention; Fig. 2, an under side view of same; Fig. 3, a sectionon the dotted line 3 3 of Fig. 1; Fig. 4, a modified form in which thenut which holds the eyebolt to which the chain is fastened ispermanently embedded in the stopper, the View being in vertical section;Fig. 5, a like section of a second modification; Fig. 6, a like sectionof a modified form in which the eyebolt is permanently secured to thestopper; Fig. 7, a view in section of a modified form embodying featuresof the construction shown in Figs. 3 and 5, and Fig. 8 a modification inwhich the eyebolt to which the chain is fastened is held in place by apin.

Like letters of reference indicate like parts throughout the severalviews of the drawings.

A is the disk of flexible material, preferably rubber, of sufficientlylarger diameter than the outlet-passage to be closed to overlap theadjacent surface of the bowl or tub.

B is the guide which extends equally from both sides of the disk with anoutward taper and may be of rubber made integrally with the disk, asshown in Fig. 3. Passing diametrically through the guides through asuitable perforation centrally of and at right anthe threaded end of thebolt 0 is screwed.

The enlargements l) are made at both ends of the perforation to enablethe nut to be changed from one side of the disk to the other when it isdesired to change the side of contact of the disk with the bowl. Byplacing one side of the disk constantly next to the opening the pressureof the water sags it at the middle, causing the edges to be raised outof contact with the surface around the outlet and injuring the closure.The easiest and most efficient means of correcting this is to change thecontact side by turning the disk over occasionally, as above providedfor.

To enable the bolt to be clamped securely to the guides, I provide thecap E, which is large enough to overlap the sides around the opening forthe nut.

To change the side of contact of the disk, the eyebolt O is screwed outof the nut D and withdrawn. Then the nut D is changed to the enlargementor socket b on the opposite side of the stopper and the eyeboltreplaced, but on the side opposite its first position.

In the modification shown in Fig. 4 the nut f is embedded in the rubberand saves the bother of its removal and change. The eyebolt E is screwedout of the nut and removed from the perforation at one end andreinserttwo guides and the disk are separate pieces which are heldtogether by the bolt.

In the modification shown in Fig. 7 the disk and guides are separatepieces, thelatter having enlargements or sockets as described for theconstructionshown in Fig. 3. The eyebolt H is constructed and applied inthe same manner as shown in Fig. 3, but the nut his provided with an eyelike g of Fig. 5.

In the modification shown in Fig. 6 the bolt I has an eye at each endinto which the chainring iwill be inserted and changedfrom one eye tothe other according to which side of the disk is to be under. The tWoguides are integral with the disk, and the bolt 1 has the enlargement iintermediate its ends, which is molded in the rubber, as shown. Groovesare cut across the ends of the guides to allow the chain-ring to beintroduced to the eye in the bolt.

In the modification shown in Fig. 8 a bolt J, with an eye at each end toreceive the chain-ring,is retained in its perforation in theintegrally-formed disk and guides by the pin j, which enters a suitabletransverse perforation under the disk and passes through a suitableopening in the bolt. In this form the guides are notched at their ends,like the form shown in Fig. 6, to admit the ring for the chain.

Having thus fully described my invention,

what I claim as new, and wish to secure by Letters Patent of the UnitedStates, is

1. In a stopper for washbasins and bathtubs, a flexible disk larger indiameter than the outlet-passage from the basin or tub, having atapering guide on each of its sides concentric with and of less diameterthan the disk to provide a stopper that can be reversed, substantiallyas described and'shown.

2. In a stopper for washbasins and bathtubs, a flexible disk larger indiameter than the on tlet-passage from the basin or tub, having atapering guide on each of its sides concentric with and of less diameterthan the disk to provide a stopper that can be reversed, a ring for theattachment of a chain, and means for securing the ring to the stopper atthe end of one of said tapering guides and of changing it from the endof one guide to the other, substantially as and for the purposesspecified.

In witness whereof I have hereunto set my hand and seal, atIndianapolis, Indiana, this 6th day of June, A. D. 1899. a
